win8_importing.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like win8_importing.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like FileCoAuth.exe - to follow. These files were created so that multiple programs (eg. Opera) could share the same win8_importing.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when win8_importing.dll is attempted to be loaded either when Opera is starting up, or in some cases already running. Some of the most common win8_importing.dll errors include:
- Access Violation at address - win8_importing.dll.
- win8_importing.dll could not be found.
- Cannot find C:\Users\Tester\AppData\Local\Programs\Opera\64.0.3417.54\win8_importing.dll.
- Cannot register win8_importing.dll.
- Cannot start Opera. A required component is missing: win8_importing.dll. Please install Opera again.
- Failed to load win8_importing.dll.
- The application has failed to start because win8_importing.dll was not found.
- The file win8_importing.dll is missing or corrupt.
- This application failed to start because win8_importing.dll was not found. Re-installing the application may fix this problem.
Your win8_importing.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Opera), or deleted by a malware infection. Furthermore, win8_importing.dll file corruption could be caused from a power outage when loading Opera, system crash while loading win8_importing.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
